Ericsson HK120/25
This is central battery intercom with line selector for 25 lines and all of them can be used also to call switchboard.
I did not find the serial number, but the model can be found from Ericsson catalog from 1930. The ones with bakelite handset must be newer. On the bottom there a paper label with hand written date 9/10/1961.
